Flooding has left about 100 people northwest of Ottawa living temporarily on an island.

Sandbags protecting a neighbourhood in the Lacroix Bay area near Pembroke, Ont. were overwhelmed in recent weeks when the Ottawa River rushed in, leaving residents completely surrounded by water.

Now, they can only access their homes by boat.

鈥淚t鈥檚 a challenge,鈥 resident Lynda Rose told CTV News. 鈥淲e all take turns using the boat.鈥

Rose only visits her home on weekends to drop off groceries and other supplies for her husband, who stayed back to help other residents and care for the family cat.

Kevin Collins said the waters just keep rising.

鈥淚t will take two weeks to even go down to 2017 levels where you might be able to start using the road again,鈥 he said.

The City of Pembroke declared a state of emergency on Thursday and soldiers from a nearby base were deployed Saturday to protect homes. Soldiers worked together to build a sandbag wall at a park near the water.

About 25 homes are at risk. Shawn Bergeron鈥檚 is one of them. His family built a retaining wall around their home after flooding in 2017, but now the wall is under water.

鈥淚t鈥檚 very scary,鈥 he said.

Last night, the Bergerons received news that their insurance will not be renewed.

鈥淜nock on wood we don鈥檛 need it,鈥 he said. 鈥淏ut it鈥檚 just a kick in the you-know-where at the wrong time.鈥

Melting snow and heavy rainfall have triggered spring floods in communities across Ontario, Quebec and Atlantic Canada in recent weeks.
